Gamma-rays in flat-spectrum AGN: Revisiting the fast jet hypothesis with the CJF sample

Understand

The recent release of the First Fermi-LAT Source Catalog solidified the predominant association of extragalactic gamma-ray emitters to active galaxies, in particular blazars.

• A tight connection between AGN jet kinematics and gamma-ray properties has been argued for, attributing the energetic emission from active galaxies to their highly relativistic outflows.
• We investigate the Caltech-Jodrell Bank flat-spectrum (CJF) sample to study the connection between AGN jet kinematics and their gamma-ray properties.
• The high number of sources included in the sample, in addition to the excellent kinematic data available, allows us to investigate the origin of gamma-ray emission in AGN.
